` Application filed February 24, 1913. Serial'lo. 750,092.

To all whom it may concern.'

Be it known that I, FERDINAND J. TiLL- MAN, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Adding-Machines, of which the following is a specification.

The primary object of this invention is to provide an improved calculating machine that is s1nall,simple, and inexpensive, and can easily be carried. I

Another object is to provide an adding machine of this character in which the envwhereby the sum, or total, after being selected, is held in a row for' inspection until recorded.

Other and further objects will appear in the specification, ahd be specilically pointed out `in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Fig. 3 is a transverse vertical section taken on the line lll-11H, Fig. 1. Fig. a is a vertical section of a portion of this improved adding machine, taken' on the line lil-117, Fig. 1. Fig. 5 is a section on the line V-V, Fig. 3. Fig. 6 is a4 section taken-on the line -VI-VI, Fig. 5. I Fig. 7 is a fragmentary plan view, parts being shown `in section, taken on the line VII- VIL Fig. 1.. Fig. 8 is a fragmentary perspective view, partly in section, showing a portion of the stop bar and its attachments. Fig. 9 isa portion of a longitudinal section of this improved adding machine, similar to Fig. 1, some of the parts being shown in shifted position.

Referring to the drawings: 1 designates a casing which is mounted on the feet 2, said casing having the side walls 3, front wall'LL, and end wall 5. It is to be noted lthat the front wall 4l does not extend downwardlyv the full' depth of the casing, there being another front wall 6 formed on said casing at a distance in from the front wall el. Between the said front walls el and 6, and adjacent their lower and upper ends, respectively, is formed an opening 7. The casing 1 also has a top wall 8,and a bottom wall 9.

. Formed in the top wall 8, 'adjacent the center thereof, is a rectangular opening 10. Formed on the front wall et and end wall 5, on the inside and adjacent the top thereof, are a series of 4supporting sockets y11, said sockets being in longitudinal alinement with each other, and adapted to secure a series of trackways 12 thereto. Mounted on said trackways 12are a series of selector bars 13, saidselector' bars being normally held toward the rear of the casing by helical springs 11. Said springs are secured at one end to the end wall 5, as shown at 15, and are secured to the selector bars on their under side by the screw eyes 1G. Said selector bars abut at theirl rear ends against a cushioning strip 17, which cushioning strip is mounted Aover the trackways 12 adjacent the supporting sockets 11 of the end wall 5.

Formed on the under side of each selector bar is a series of rack teeth 18,'which series of rack teeth are adapted to engage with the pinion l19. Said pinions are mounted on a horizontal shaft 20. Formed integral with each pinion 19, and on one side thereof, is a hub 21, said hub having outstanding arms on which is mounted the spring actuated pawl 23. Said pawl is adapted to engage the teeth of the ratchet wheel 24, which ratchet wheel is secured to the transmission gear 25.

Mounted between each of the pinions 19` and transmission gears 25, on the shaft 20, are spacer sleeves 26. Meshing with each transmission gear 25 are gears 27, each of said gears 27 being secured to the totalizing wheel 28. Formed on one side of each totalizing wheel is a hub 29. Formed on each hub 29 is an intermittent wheel 5l). All of said parts 27, 28, 29 and 30 are loosely mounted on the horizontal shaft 31. Said shaft is journaled in the bearings 32 formed on the side walls 3. h

Depending downwardly from the rear ends of each of the selector bars 13 is an extension 33. Pivotally mounted to each of said extensions, at one end, as shown at 34,

is a combined stop and numeral bar 35, each I of said bars 35 being supported at its oppositeend by a spring 36. Said springs are supported from the forward end of the selector bars 13. c

Extending transversely across the top of the adding machine, adjacent the forward end of the rectangular opening 10, is a recording bar 37. Said recording bar has a depending portion 38 on each side. Each of said depending portions extends downwardly to a point below the selector bars, and then converges into a horizontal portion 39. Said horizontal portion, at its end,

is pivoted to the side Walls by pivots 40. Connecting said horizontal portions 39, and extending transversely across the casing 1, is a combined retaining and striking bar 41. In order to hold the recording bar 37 in an inactive position a pair of springs 42 are used, each of said springs connecting With each depending portion 38, and being secured tothe under side'of the top Wall 8 by screw eyes 43.

Located adjacent the forward end of the rectangular opening 10, and also adjacent the recording bar 37, is a stop bar 44. Said stop bar is adapted to extend the full Width of the rectangular opening 10, and has depending portions 45 adjacent its ends. Said depending portions are pivoted adjacent their centers at 46 to the side Walls 3. The lower ends of said portions 45 are pivoted at 47 to the side portions 48 of an engaging bar 49. Said side portions 48 are slidably mounted in guides 50.

Located under and adjacent the forward endof the stop and numeral bar 35 is an inking roller 51 Which is revolubly mounted on the shaft 52, and svvingingly mounted to the side Walls 3 by supporting bars 53. Said'supporting bars 53 are pivoted at one end to said side Walls, as shown at 54. Springs, such as 55, are secured to said supporting bars 53 to hold said inking roller 51 in engagement with the numeral blocks 56 which are formed on the under side of the bars Formed on the upper side of each of said bars 35 are a series of engaging members 57 said members being disposed on said bars opposite to the numeral blocks 56.

*1, parallel With and adjacent the numeral Wheels 28, is a striking bar 62. Said striking bar is swingingly mounted on the shaft 63, which is supported in the side walls 3, and is held in an inoperative position by springs 64. Said springs normally hold the said striking bar against stops 65. Formed adjacent the center of said striking bar is an outstanding lug 66. Said lug is adapted to be operated upon by a striking lever 67, which is securely mounted on the shaft 68. Said shaft, at one end, extends outside of one of the sidewalls 3, and has mounted thereon a lever 69. 4

Mounted upon a transverse shaft'70, adjacent the center of the casing l, is a roil of paper 71, which is adapted to be printed upon during the operation of the machine. The paper passes under guide rollers 72, one of said guide rollers being mounted on the shaft 63 of the striking bar 62. Continuing, the' paper passes between a roller from said bar are a series of pins 77 on` `which are mounted a` series of spring actuated paWls 78. The retaining portions 79 of said pawls are adapted to engage against one side of each bar 35. Formed on top of each bar 35, adjacent the point of engagement, of the retaining vportion .7 9 Lf the paWl 78 are inclined-cutaway portions 80, which is more clearly shown in Figs. 2 and 4. Located adjacent the under side of the totalizing Wheels 28, and bearing against said Wheels, is an inking roller 81.

In the operation of this improved adding machine, assume that the first number of a column of figures to be added is 345. Said number is selected on the iirst three selector bars to the right. As the fingers of the hand are directed to one or all of the selected numbers, each finger will engage one ofthe projections 82. There are a series of these projections on each of the selector bars 13. The selector bars are drawn toward the front of the machine until the lingers of the operator engage against the stop bar 44. .As each selector bar 13 is moved, the teeth 18 formed on the under side thereof will engage a pinion 19. By reason of each pinion 19 having a hub portion 21, the pawl 23 that is carried by said hub portion' will engage the ratchet Wheel 24, which ratchet Wheel Willthen carry the transmission Wheel 25. Said transmission Wheel 25 Will then rotate the totalizing Wheel 28 through the gear 27. Itis to be noted that when each selector bar is moved it carries with it the combined stop and numeral bar 35. In the instance of carrying the selected numeral 3 said numeral will be drawn toward the front of the machine'until stopped by the operators nger engaging the stop bar 44. One of the engaging members 57 formed on the bar 35, which engaging member is designated as 83, will be engaged against the striking bar 41, which will holdthe selector bar in position until after recording. It is to be noted that the number of engaging members 57 is equal to the number of numeral blocks 56, as well as the engaging members 82. So that whatever number is selected on any selector bar, said selector bar is moved forward to its limit of movement. One of the engaging members 57 will hold the selector bar in its moved position by its engagement with the striking bar 41. Whenever a number has been selected on the selector bar, and the se lector bar has been moved, one of the numeral blocks 56, bearing a number corresponding with the number selected, will be carried forward by the bar 35 and will remain in the recording position over them` roller 58. After the selector bars, bearing the selected numbers 3, 4, 5, have been moved forward and are held in position for recording by the operation just described, the recording bar 37 has a pressure brought to bear upon it, and the striking bar y41 will be carried downwardly, bearing down the bar 35. The numeral blocks 56, carrying the numerals 3, 4, 5, will bear against the paper sheet, which paper' sheet is engaged over the upper periphery of the roll 58, andthe numerals 3, 4, 5, will be printed thereupon. When the pressure is relieved from the recording bar 37, the springs 42 will return said recording bar to its normal position, and the spring actuated pawls 61, which are carried by said recording bar, will engage the ratchet wheels 60. This will then turn the paper sheet on which the numbers have been recorded a space so as to be ready for the next elected number. At the time the striking bar 41 depressed the bars 35, said bars were depressed to such an extent that the top portion thereof was engaged by a portion of their respective spring actuated pawls 7 8. As .the striking bar 41 was returned to its normal position, the bars 35 of the three selected numbers were held down so that the engaging portions 57 of said bars could pass under the striking bar 4l, as said bars 35 and the selector' bars 13 are returned to their normal position by the springs 14. At this point the cutaway portions 8O formed on the upper portion of the bars 35 will be in alinement with the spring actuated pawls 78 so that the retaining portion 79 of said pawls will slide off from said bars 35 upon their engagement with said cutaway portions 80.

gers, upon engaging the stop bar 44, will move said stop bar, thus carrying the engaging bar 49 into engagement with the teeth of the transmission wheels 25. This is merely to stop the momentum from carrying the transmission wheels beyond their intended distance. Each of the transmission wheels 25 has mounted thereon a prof jection 84, which projection, upon continued operation of the selector bars in the. order of adding, will engage with .its respee tive intermittent wheel 30 so as to carry numeral wheel 28 to the next order. After a column of figures has been brought down and recorded by the actuation of the selector bars 13, and the recording bar 37, and the total is desired, the lever 69 is pressed down which will cause the striking lever G7 to be engaged against the lug 66 of the striking bar 62, which will cause the striking bar 62 to be engaged against the proper totaling numerals on the totalizing wheel. As the sheet of paper will be between said striking bar and the totalizing numerals to be recorded, the total will be printed on said sheet. After the pressure has been removed from the lever 69, the actuating parts relating to said striking bar 62 will be returned to their normal positions. The sheet of paper can then be engaged through the opening 7 ofthe casing 1, and the sheet of paper drawn forward, and a portion of the paper sheet containing the recorded figures, can then be torn olf in any suitable manner.

In the drawing forward of the selector bars 13, it is to be noted that when the operators fingers are. adjacent the stop bar 44, the rear portion ofthe operators hand will be above the. recording bar 37. So that by a mere downward movement of the heel of the hand said recording bar will be depressed, whereupon the elected numbers will be recorded, and the operating parts returned to their normal positions. There fore, it is not necessary for the operator to move his hand to any other part. of the machine. For this reason, the operation of this improved adding machine can be carried on very rapidly, which is done solely by the drawing down of the finger and the drawn down by the manipulation of the selector bars, said numbers Will be in a straight line and so held that said numbers can be checked or inspected. Also, the mere drawing forward Aol" said selector bars actuated all' the operative parts so that everything is in position for recording when said selector bars hare been drawn down to their limit of movement, Which limit is governed by the operators lingers engaging the stop bar 44.
